The high-speed bolts the Boltgun fires are able to pierce standard Helghast and ISA armor with incredible ease, sending most enemies flying backwards and pinning them to the nearest surface before finally exploding a few seconds after impact. It is only found in the Suljeva Village and Tharsis Refinery missions, usually on Miners or in weapon racks.
The Boltgun is most useful at short-mid range, as it is very effective at literally removing unwanted enemies from your immediate area. Due to the slow speed of the individual bolts, it is less useful at long range. However, an experienced player can make easy kills on enemies who poke around cover to fire. The radius of the resulting explosion is considerably small, and is only really useful on an enemy who is directly hit. Despite this, the explosion will kill any enemy it narrowly misses, as long as they don't move.
Due to the Boltgun's low ammunition reserve, it is advised to move closer to ranged enemies first before firing, to ensure that your shot isn't wasted. Taking a long range shot may leave you vulnerable to Snipers, and would be more difficult to make the shot.
In multiplayer, try to sneak in first before firing to ensure that you hit your target, and are not shot down before firing. Although it has accuracy comparable to the VC32 Sniper Rifle, it is much harder to fire with similar accuracy due to the lack of a scope and the significantly lower velocity of its ammunition, but lacks any form of drop once fired.
